NTN NS224045 Automatic Transmission Extension Housing Seal

The NTN NS224045 is a premium automatic transmission extension housing seal designed to prevent transmission fluid leaks and protect critical drivetrain components. This seal is engineered to OE specifications to ensure proper fit and reliable performance in automatic transmission applications.

Key Features:

• Precision-manufactured to meet OEM standards for exact fit and function
• Advanced seal material construction resists temperature extremes and transmission fluid degradation
• Engineered sealing lip design maintains constant contact pressure for leak-free operation
• Steel-reinforced construction provides dimensional stability and durability
• Compatible with modern automatic transmission fluids including synthetic formulations

This extension housing seal mounts at the rear of the automatic transmission where the output shaft exits the housing, preventing fluid loss and contamination entry. Proper sealing in this location is critical to maintaining transmission fluid levels and protecting internal components from dirt, moisture, and debris that can cause premature wear and failure.
